Hi
I am working on boiling in evaporators. Domain description: 1. tube body 2. inner fluid 3. fins body (fin body is modelled as porous medium) 4. external air body i am having liq- refrigerated, vap-refrigerant and air as different fluids that are to be modelled. i selected mixture model in multiphase flow with 3 phases. i specified primary phase as liq- ref, secondary as vap-ref and secondary phase as air. my question is : in the inner fluid domain there should not be any air and in the external air domain there should not be any liq and vap-refrigerant. so is this possible to model. and how to model porous medium with air flowing in with out any refrigerant. this model is working fine in single phase flow .... i am new to use multi phase model. so can any one help in this. Regards, Premchand |
